"The ceremony took place in one of Chicago's most historically significant buildings, The Rookery," a guest tells Life & Style. "They're so happy!"

Following the ceremony, a post-cocktail reception began at 5 p.m. Guests, including former Amazing Race contestants Ron Zeitz, Bill Smith, Justin and Jennifer Young and Marie and Liz Canavan, were transported via trolley to the gorgeous reception at another famous Chicago landmark, the Chicago Cultural Center.

Cindy wore a beautiful Jorge Perez de la Habana gown with sparkly Badgley Mischka heels, while Ernie looked dapper in a traditional black tuxedo. The bridesmaids wore plum-color dresses with gold accents, and all the men wore special socks that looked like the Bavarian flag, in honor of the groom.

"It was a vintage-travel theme, with wedding programs inspired by passports," the guest reveals to Life & Style. "Framed vintage travel posters [decorated the] trays for the hors d'oeuvres during the cocktail reception, and stacked vintage luggage was used for the gift boxes. It was really cool."

Bride and Groom

After covering four continents and 20,000 miles to win The Amazing Race (and $1 million) last season, Cindy Chiang, 30, and Ernie Halvorsen, 29, embarked on a new journey March 10, getting married in Chicago.

A Million Dollar View

Wearing a gown by Jorge Perez de la Habana and sparkly shoes by Badgley Mischka, Chiang's special day took place in two landmark buildings in the couple's hometown. The ceremony happened at The Rookery, followed by guests traveling on a trolley to the Chicago Cultural Center for dinner and dancing at the reception.

Amazing Setting

In the stunning lobby of The Rookery, the couple were married in front of guests including Amazing Race contestants Ron Zeitz and Bill Smith, Justin and Jennifer Young, and Marie and Liz Canavan. The bridesmaids wore plum-colored dresses and gold accents. The black tux-clad groomsmen donned socks patterned after the Bavarian flag in honor of Halvorsen, who had lived in Germany for work.

Father of the Bride

Chiang's father Dr. Dalen Chiang walked the bride down the aisle for the wedding with – what else? – a travel theme, with passports for programs, a departure board telling dinner guests where to sit and menu cards that looked like telegrams in vintage envelopes.

Cake Topper

The bride and groom are depicted in their Amazing Race gear atop a small cake. Guests at the reception enjoyed crusted filet of beef and chicken breast stuffed with apple, currant and caramelized onions and caraway. Desert was chocolate and raspberry custard wedding cake and treats of chocolate-covered bananas and chocolate cheesecake lollipops.

Ernie and Cindy Halvorsen, who won the long-running reality show in 2011, welcomed their second son, Ernest Zhang Halvorsen, they confirm to PEOPLE.

The new baby joins 21-month-old big brother Maverick Zhang.

Ernest, who was born in Chicago on Tuesday, July 19, weighed in at 8 lbs. and was 20 inches long. He came into the world at 7:06 p.m.

“Our second-born carries the name Ernest into a fifth generation of Halvorsen men,” Cindy tells PEOPLE alongside the exclusive birth announcement. “We’re calling him ‘Finn,’ which is an old nickname for the five-dollar bill.”

Predictably, the family is thrilled with the new addition — but no one is happier than Maverick, who turns 2 in October.

“Maverick is the sweetest big brother,” says Cindy. “He loves to hug and kiss Finn! We’re exploding with happiness as a family of four.”

“Creating our family together is our greatest and most fulfilling adventure,” she continues. “We’re so lucky to be parents to these two amazing little boys who fill our hearts with love and laughter.”
